Measurement and Instrumentation Potentiometer method of DC voltage measurement is more accurate than direct measurement using a voltmeter because It does not load the circuit at all. It loads the circuit moderately. It uses centre zero galvanometer instead of voltmeter. It loads the circuit to maximum extent. It does not load the circuit at all. It loads the circuit moderately. It uses centre zero galvanometer instead of voltmeter. It loads the circuit to maximum extent. ANSWER DOWNLOAD EXAMIANS APP

Measurement and Instrumentation If two meters X and Y require 40 mA and 50 mA respectively, to give full scale deflection, then Y is more sensitive. It would not be possible to assess the sensitivity on the basis of the given data. Both X and Y are equally sensitive. X is more sensitive. Y is more sensitive. It would not be possible to assess the sensitivity on the basis of the given data. Both X and Y are equally sensitive. X is more sensitive. ANSWER DOWNLOAD EXAMIANS APP
